Depending on your usage and location a hobby welder could save up to 80% on shielding gas. Gas comparisons (mild steel MIG) Gas comparison for DIY mild steel (on main site) Comparison between CO2, Argon/CO2 mix, and pure Argon. CO2 Thin Metal Warning Beware when welding 1mm or less on low settings - CO2 can fail to maintain a workable arc. Detailed comparison of percentages of Argon and CO2 (Shenion's website) Shenion varies the gas mix at 10% intervals from 100% Argon to 100% CO2. Wow! Argonshield Member changes from CO2 to an argon/CO2 mix. Notices a difference. Welding gas reference (main site) A quick lookup by Omniata showing the composition of different BOC and Air Products gasses. Weld faults due to shielding gas Welds collapse in frothy heap Includes photos of porous welds and one good one. Welding outdoors in the wind or poor flow from disposable regulator might have been the trouble. Regulators How to judge correct gas flow setting If you only don't have a flow gauge on your regulator you'll need a peashooter to measure gas flow. Freezing regulators on CO2 Some non-welding CO2 bottles suck up liquid from the bottom with a tube. Gas Economiser (Argomiser/Argosaver) Photos of gas economisers and why Chinese regulators cause exprosions. Disposable bottles How long do they last? Not very long at all. A 60L bottle running 10L/min would last for 6 minutes (1m of weld). Connecting the welder to the regulator How to fit and remove the plastic pipe. Disposable regulator and gas bottle problems Covers some bottle problems as well as regulator problems. Safety Shielding Gas Cylinder Safety Woz's well researched post covering aspects of bottle identification, handling, use, disposal and many more dos and don'ts. Transporting gas bottles Rules and regulations for transporting bottles. Use the right gas in the right cylinder Some info about why not to fill a cylinder with a different gas. How to fit a regulator How to safely fit and set up a regulator on an industrial gas cylinder ---------------------------------------------------------------- Moderators feel free to edit this post to link to further threads.
